Push the ultimate limits of human endurance at the 24 Horas a Correr Mem Martins - Sintra, a legendary day-and-night running challenge returning for its seventh edition on May 9–10, 2026. Set in the heart of the Sintra municipality, this event is far more than a standard race; it is a monumental test of physical and mental fortitude. Runners from across the Iberian Peninsula and beyond gather in Mem Martins to see how many kilometers they can conquer within a fixed timeframe, pushing through the fatigue of the night and the rising sun of the Portuguese spring.
The 2026 program is designed to be inclusive of all endurance levels, offering a versatile range of challenges. Participants can commit to the full 24-hour epic, test their stamina in the 12-hour or 3-hour events, or take on the high-intensity Maratona Noturna (Night Marathon). The race takes place on a controlled circuit, providing a profoundly supportive environment where every lap is met with the cheers of local spectators and fellow competitors. This format turns individual struggle into a shared community celebration, making it an ideal entry point for those looking to break into the world of ultra-marathoning.
Organized with deep local roots and a commitment to pure perseverance, the 24 Horas a Correr Mem Martins offers professional logistics, including dedicated support zones, frequent chip-timed updates, and a constant supply of energy to keep you moving. In this arena, the clock is your only true competitor, and the finish line is not a physical mark but a testament to your own will. Whether you are aiming to qualify for elite ultra-titles or simply want to discover what your body is capable of over 24 hours, secure your spot in Sintra for an unforgettable journey of self-discovery and athletic triumph.
